Most permanent magnet synchronous motor has feedback transducer, and the importance of the temperature rise control of motor is by most of cognitions, and it is that the thermal diffusivity design is first-selected that motor adds fan blade.At present the mounting structure form of a kind of synchronous motor feedback transducer with cooling system of prior art and the problem of existence: central screw fixedly feedback transducer, cooling system adds separate fan: this structure employing central screw is fixed on feedback transducer on the shaft of motor, provides the independent current source of two-phase to add separate fan.This structure can't add coaxial fan blade can only add separate fan.And separate fan is subjected to the restriction of installing space, and the air output of this fan is than little many of the fan of the standard coaxial of motor, thereby can cause the not good motor overall performance of motor radiating.Need the independent current source of two-phase that outside plant is required to improve in addition, cost improves.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and provide a kind of practicality, reliably, cheaply with the mounting structure of coaxial fan blade synchronous motor feedback transducer.
The technical scheme that its technical problem of the utility model adopts: this mounting structure with coaxial fan blade synchronous motor feedback transducer, mainly comprise rotating shaft, inlay little axle, sensor stator, rotor sensor and motor blower fan, inlaying little axle is connected by the shaft hole location with rotating shaft, rotor sensor is fixed on to be inlayed on the little axle, sensor stator is positioned at outside the rotor sensor, motor blower fan is placed in fan blade mosaic set external fixation and is integral, motor blower fan and fan blade mosaic set are fixed on to be inlayed on the little axle, and rotating shaft is provided with electric motor end cap.
The hole of described electric motor end cap cooperates with the cylindrical of sensor stator location.
Described motor blower fan and fan blade mosaic set link into an integrated entity by key, and by nut motor blower fan are fixed on and inlay on the little axle.
Locate with inlaying little axle in the hole of described rotating shaft, and be connected with sunk screw with the rotating shaft screw by the uniform counterbore of inlaying little axle disk end face.
Describedly inlay little axle and be integral by screw with rotating shaft.
The effect that the utility model is useful: the utility model adopts rotating shaft and inlays little axle cross-compound arrangement, has reduced material and processing cost, and it is convenient that simultaneously simple and practical reliable and technology realizes.Simultaneously this organization plan adopts the standard fan blade of motor, the die sinking cost of reduction with the mode of fan blade mosaic set.
